' LUBRICA'IING Device. I 7

To all whom it may concern:

Be it known that I, W'ILLIAM MCLAUGH4 LIN, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification, reference be1ng had to the accompanying drawings. I

This invention relates to new and useful improvements in lubricating devices .and

more particularly to a device of this character which is generally applicable to carwheels and the like, the main object of the invention being the provision of a lubricating system whereby the axle and journal.

bearing of a car wheel or the'like may be readily lubricated. I 7

Another object of the present invention is the provision of a lubricating device of the I above character which will possess advan tages in points of efliciency and durability, is inexpensive to manufacture and one which will be very efficient and useful in operation.

With the above and other objects in view, the invention consists, in the novel features I of construction, combination and arrangement of parts as Wlll be hereinafter referred to and more particularly pointed out 1n).

the specification and claims.

In the accompanying drawing forming a part of this application, Figure 1 is a transverse sectional view taken through the hub of a wheel illustrating my improved lubricating system. Fig. 2 is an end elevation of the hub. Fig-3 is a longitudinal-sectional view through the hub; and 4: is a transverse sectional view taken on the line l4, Fig. 3.

As disclosed in the accompanying drawings, 1 denotes anaxle with which is rotatably engaged the hub 3 .of the'wheel 2.

The wall of .the bore 4: of the hub is pro vided with the spaced longitudinally dis posed grooves 5, the outer extremities,there- I of being in communication with the annular oil cellar 6, the walls of which converge toward the outer end of the hub.

The inner extremities of the grooves 5 are partially'closed by the nwardly directed lips 8 positioned at the bases ofthe grooves,

whereby the discharge of the lubricant between the hub 3 and the bearing collar 9, suitably affixed to the axlel, will be re- Copies of this patent may be obtained for Specification of Letters Patent.

artto which "my invention appertains. It

is-to be observed that the maximum diameter of the cellar 6 is such as to have the bases or bottoms of the grooves 5 substan-v With the inner margin of the tially flush cellar.

simple lubricating device which can be applied to'a'ny of the general forms of car wheels at a very small cost and will save considerable time and money in changing It'willbe noted that Ihave provided a i the old wheels, whichhave become worn, I

for new ones. It will be noted from the accompanying, drawings, that the grooves 5 all extend in one general direction :but'it will be' 'apparent that they may extend in e ther direction or half extend in one direct1on and the other half in the other direction.

g VVhi'le I have shown and describedthe preferred-fo'rm-of my invention,it will beobvious that variouschanges in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice, without sacrificing any of the novel features or departing from. a

the scope of the appended claims.

Having thus described this invention,

what I claim is 1. A wheel including a hub, the bore I I thereof at one extremity being enlarged to afford an oil cellar and having a plurality of longitudinally disposed spiral grooves arranged therealong and in communication at one of their ends with the oil cellar, the opposit'e ends of the grooves being closed.

2. A wheel including a hub, the bore thereof at one extrem ity*beingenlarged to afford an oil cellar andhaving a plurality partially of longitudinally disposed spiral grooves arone of their ends with the oil cellar, and lips ranged therealong and in communicationat' V l .100

projecting inwardly from the bottoms of the grooves at their oppositeends and partially closing such ends.

'In testimony whereof Ihereunto affix my signature in the'pr'esen'ce of two witnesses.
